Horizontal registration operation
The punch slide unit is driven by the punch slide motor (M101) to perform horizontal
registration. The home position of the punch slide unit is detected by the horizontal
registration HP sensor (S101). The punch slide unit detects the leading edge of the media
with the inlet sensor (S106) and horizontal registration sensor (LED1 to 5 on the LED PCB,
PT1 to 5 on the photosensor PCB) and moves to the trailing edge of the media according to
the media size. The horizontal registration operation is as follows:
1) When the leading edge of the media is detected by the inlet sensor (S106) of the puncher
unit, the punch slide motor (M101) starts to move the punch slide unit to the front side.

2) After the horizontal registration sensor (LED1 to 5, PT1 to 5) detects the far end of the
media with the size signal sent from the host machine, the punch slide motor (M101) drives
further to the front side prescribed position and stops the punch slide unit.
